THRAS'HING-MACHINJE.

SPECIFICATION forming part of Letters Patent No. 293,019, dated February5, 1884.

Application filed November 1, 1893.

To all [0710772 itma concern,

Be it known that I, ANDREW T. IL-uvLnY, of Alton, Madison county, andState of Illinois, have invented a new and Improved Thrashing-Machine,of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and useful improvement inthrashingmachines,wherebywaste of grain is prevented, and the grain isthoroughly separated from the straw. I

The invention consists in various parts and details of construction andcombinations of the same, as will be fully described and set forthhereinafter.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a thrashing-machineprovided with my improvements, parts being broken out. Fig. 2 is alongitudinal elevation of the heavy beater, parts broken out. Fig. 3 isa crosssectional elevation of the same on the line w a, Fig. 2. Fig. 4is a longitudinal elevation of the light beater, parts beingbroken out.Fig. 5 is a cross-sectional elevation of the same on the line y y, 4.

The thrashing-cylinder A is journaled at the end of the box, in theusualmanner. A short distance within the box a heavy beater, B, isjournaled, and a short distance from the same a light heater, 0, isjournaled, the light beater .0 being located considerably higher thanthe heavy beater B. Between the heaters B and C a guard, D, is located,which is inclined downward from the top of the boxxin 'the directionfrom a point above the heavy beater B to a point below the light beaterO. The heavy beater B is constructed with four wings formed of boardsabout seven-eighths of an inch thick, the beater being eleven inches indiameter. The said boards or wings E are attached to a cast-iron head,F, in the manner shown in Figs. 2 and 3, and are covered with heavysheet-iron, a, and are provided with a casting, G, secured on the outeredge, from which casting spikes H project, which are about one inch longand about four inches apart. The spikes are so arranged that those I onone wing set centrally between the spikes (No model.)

ll on the next wing, or in staggered positlon lengthwise andcircnmferentially of the beater. The wings are securely tenoned to thecast heads F. The light beater O is thirteen inches in diameter, and isprovided with four wings, J, bolted to a square shaft, K, and braced bybraces L. The beater B is revolved in the reverse directioh of thethrashing-cylinder A, and the beater O is revolved in the reversedirection of the beater B. The heavy beater B catches the straw from thecylinder A before it has a chance to fall, and throws it into the spaceabove the beater, from which space it has a fall of about twenty-eightinches, the guard or deflector D guiding the straw downward. The smallerbeater O,'running in the opposite direction of the beater B, strikes thestraw while it is falling, and assists the separation of the grain fromthe straw. The two beaters also prevent the cylinder from throwing thestraw over the fingers without being thoroughly handled by the saidfingers.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A thrashing-machine constructed with a heavy beateradjoining the thrashing-cylinder and'revolving in an opposite directionthere to, and a light beater adjoining the heavy beater above and inrear of it, and revolving in an opposite direction thereto, whereby thestraw will be received from the cylinder by the heavy beater and thrownupward, and as it falls be subjected to the action of the light beater,substantially as herein shown and described.

2. In a thrashing-machine, the combination, with the thrashing-cylinderA, of the heavy beater B, adjoining the cylinder and revolving in adirection opposite thereto, the light heater 0 adjoining the heavybeater B above and in rear of it, and revolving in an opposite directionthereto, and of the downwardly-inclined guard or deflector. D betweenthe heaters B 0, whereby the heavy beater B will receive the straw fromthe cylinder and throw it upward against the deflector, and as it fallsbe subjected to the action of the light beater, substantially as hereinshown and described.
